I had a minor rust issue on the P7 that I carry from a day that I was wearing it and sweating bad. Had just a bit forming on the left side at the back of the slide where it would stick up just above the leather of my holster.
Anyway, I had it all apart the other night, cleaned off the rust, etc.. I had read that EEZOX provided some protection after it dries, which sounded ideal for a carry gun. So I applied the EEZOX, perhaps slightly heavier than I should have, but still not too heavy. The only reason I say maybe heavier than I should have is that I let it dry overnight, and the next day I found parts that were still wet. I wiped everything down, reassembled, and now the slide is a fair amount more stiff than it used to be. I can pull the slide back, but it takes quite a bit more force than it used to.
I've put about 70 rounds through it so far since. I haven't had a single failure of any kind. I can't tell if the shooting loosened it up at all, it may have slightly, but not much. I can't actually see any hard residue anywhere. I guess I could brush the rails with some steel wool and see if that makes a difference.
Anyone have this issue with this stuff? Any ideas how to rectify the situation?
